Building element and structure

ABSTRACT

A precast concrete building element and structure constructed from such elements, the elements being designed so that either face of the element can be used in the design of the construction of retaining walls, foundations, posts or other structures, wherein one face of the element gives the appearance of a dual vertical octagon shape, and the other face of the element is vertically flat faced, with a 45 degree vertically angled corner on each end of the element. Thus, the overall wall or structure gives the appearance of repeating vertical part octagonal shapes. Through various configurations of such a design, arrangements of elements to form structures which have an internal angle of 45, 90 and 135 degrees are possible. The structure can be designed so that it can be stacked straight up, in that each element comprising the structure has a groove or channel on a bottom of the element, which internally extends a length of the element, and a top surface of the element has two button shaped protrusions thereon. The protrusions are designed to allow each element to lock or connect into the groove or channel of another element placed thereon.

FIELD OF THE INVENTION

The present invention relates to a precast concrete building element and structure constructed from such element. In particular, this invention relates to a dual faced retaining element which has been designed so that either face can be used in the design of the construction of retaining walls, wherein one face of the wall element gives the appearance of a dual vertical octagon shape, and the other face of the wall element is vertically flat faced, with a 45 degree vertically angled corner on each end of the wall element. Through use of such a design, wall constructions which have an inside or outside angle of 45, 90 and 135 degrees are possible. The element can also be used in the design of the construction of a variety of other projects and structures, including foundations, posts and other configurations.

BACKGROUND OF THE INVENTION

Retaining wall blocks and walls, for example, are used in various landscaping projects and are generally available in a wide variety of styles. There are numerous methods and materials which exist for the construction of retaining blocks and walls, and such methods can include the use of natural stone, poured concrete, precast panels and masonry. Many of these blocks, such as that described and illustrated in U.S. Pat. No. 5,513,475, have been developed with configurations having essentially the same outside surface, that is a rectangular block. A standard cement block is rectangular in shape and has two openings with a solid web transversing between the two openings. However, use of these types of blocks for the construction of retaining wall structures are generally not aesthetically appealing.

Presently, when rectangular cement blocks are used to fabricate walls, the aesthetics of the wall leave much to be desired, in that essentially only a straight linear wall with a vertical surface is created. Generally, only 90 degree corners can be used if a turn in the wall is required. Other walls of various angles can be constructed only by cutting the corners of the rectangular block to match the desired angle. However, this technique is very time consuming in that it requires a skilled mason to cut each and every block at the desired angle.

More recently, segmental concrete retaining wall units, which include dry stacked individual blocks, have become widely accepted in the construction of retaining walls. Retaining walls made from these types of blocks or units can be structurally sound, easy and relatively inexpensive to install, and couple the durability of concrete with the attractiveness of various architectural finishes available for the concrete blocks. Currently, many commercially available blocks are symmetrical and include parallel front and back faces and non-parallel, converging side surfaces. The converging side surfaces allow the blocks to be stacked and form a predictable pattern for the retaining wall. However these types of blocks do not provide for a unique appearance and configuration with respect to the corners incorporated into the retaining wall.

Accordingly, there is a need for a retaining wall element and system wherein the face of the retaining wall, and the corners incorporated into the retaining wall, have a more attractive, unique appearance and variable configuration than that available in conventional wall constructions. The present invention satisfies this need and provides these benefits. In addition, the element described in the present invention can be used in the design of the construction of a variety of other projects and structures, including foundations and posts.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a dual faced building element designed so that either face of the element can be used in the design of the construction of retaining walls and other structures such as foundations, posts and other configurations.

Another object of the present invention is to provide a dual faced building element wherein one face of the element gives the appearance of a dual vertical octagon shape, and the other face of the element is vertically flat faced, with a 45 degree vertically angled corner on each end of the element, whereby through use of such a design, constructions which have an internal angle of 45, 90 and 135 degrees are possible through manipulating various arrangements of elements with adjacent elements.

According to another aspect of the present invention there is provided a building element for use in the construction of elevated structures comprising: a front face comprising first and second halved portions, each of the halved portions being substantially part octagonal in shape; a substantially planar rear face which extends substantially the length of the first and second halved portions; first and second sides; a channel formed internally on an underside of each of the halved portions of the element; and a protrusion projecting from a top surface of each of the halved portions of the element, the protrusion being dimensioned slightly narrower than the width of the channel and being capable of insertion into the channel of another wall element so as to secure the elements together.

According to another aspect of the present invention there is provided a building element for use in the construction of elevated structures comprising front and rear faces; a channel formed internally on an underside of the element; a protrusion projecting from a top surface of the element, the protrusion being dimensioned slightly narrower than the width of the channel and being capable of insertion into the channel of another element, so as to secure the elements together; first and second sides; and first, second, third, and fourth diagonal sides, wherein the front and rear faces are disposed approximately parallel to each other, the first and second sides are disposed approximately parallel to each other, the first one of the diagonal sides being disposed between the front face and the first side, the second one of the diagonal sides being disposed between the front face and the second side, the third one of the diagonal sides being disposed between the rear face and the first side, and the fourth one of the diagonal sides being disposed between the rear face and the second side.

According to a still further aspect of the present invention there is provided an elevated structure comprising a plurality of mutually juxtaposed and interconnected building elements as defined herein.

According to another aspect of the present invention there is provided a method of assembling an elevated structure in which the structure comprises a plurality of selectively juxtaposed and interconnected building elements, the method comprising the steps of providing a first building element, having front and rear faces; a channel formed internally on an underside of the element; first and second sides; and first, second, third, and fourth diagonal sides, wherein the front and rear faces are disposed approximately parallel to each other, the first and second sides are disposed approximately parallel to each other, the first one of the diagonal sides being disposed between the front face and the first side, the second one of the diagonal sides being disposed between the front face and the second side, the third one of the diagonal sides being disposed between the rear face and the first side, and the fourth one of the diagonal sides being disposed between the rear face and the second side; and, the method including the steps of positioning the first building element adjacent to one or a plurality of other building elements along one or more diagonal sides, and providing a plurality of internal corner angles formed by the face of the first building element and an adjacent face of one or a plurality of other building elements, and marshalling arrangements of a plurality of building elements with adjacent building elements along one or more diagonal sides, and positioning a protrusion projecting from a top surface of a building element, being dimensioned slightly narrower than a width of the channel and being capable of insertion into the channel of another building element, and inserting the protrusion into the channel of another building element, and securing the interconnection between the protrusion and the channel of the building elements, and arranging a plurality of building elements by securing the protrusion of one or more building elements into the channel of one or more building elements, and thereafter positioning a plurality of building elements along a plurality of adjacent diagonal sides, channels and protrusions, thus providing an elevated structure formed of the elements.

In the method described above, the corner angles are commonly formed at 45, 90 and 135 degrees respectively.

The building element of the present invention is designed so that either face of the element can be used in the design of the construction of structures, such as retaining walls, wherein one face of the element gives the appearance of a dual vertical octagon shape, and the other face of the element is vertically flat faced, with a 45 degree vertically angled corner on each end of the element. In a construction of this type, essentially, one face of the element does not complete the octagon, rather a flat surface extends the length of the two halves. The primary advantage of this design lies in its versatility. A user may arrange the stone in a variety of fashions which result in a wide ranging finished product, such as a complete wall. Through various configurations of such a design, arrangements of elements to form wall constructions which have an inside or outside corner angle of 45, 90 and 135 degrees are possible. The element can also be used in the design of the construction of a variety of other projects and structures, including posts and foundations.

Preferably, the element is made of precast concrete. In addition, each element has a singular groove or channel running horizontally across a substantial area of the bottom surface of the element, and which is internally formed on an underside of the element. Preferably, the vertical height of this groove or channel within the element extends internally to accommodate the entire vertical height of the protrusion. It is possible, however, that a shallower internal channel or groove may also be used. It is also possible that multiple grooves or channels can be formed on the underside of each element, the grooves or channels substantially corresponding in shape with the protrusions formed on the top surface of each element. The grooves or channels in each element can be internally located beneath each protrusion, whereby each protrusion from one element may be interlocked with a corresponding channel of another element placed thereon.

In a preferred embodiment of the present invention, there are two protrusions formed on a top surface of each element. Preferably, these protrusions are round and button shaped, however, other configurations and shapes can be utilized as well. The protrusions are designed to allow each element to lock or connect into the groove or channel on the underside of another element placed thereon. In this manner, building elements comprising the elevated structure can be stacked straight up in forming a complete elevated structure, and increases the strength and durability of the structure.

When completing a wall construction utilizing the building elements of the present invention, it is preferable, in constructing the top surface of the wall, to utilize a further embodiment of the retaining element of the present invention, which does not possess any protrusions on a top surface portion of the element (a “capping” element) so as to provide a substantially planar top surface for the structure.

Though generally speaking it is preferable for an elevated structure constructed with the elements of the present invention to feature full size elements wherein one face provides the dual vertical octagon shape, and the other face of the element is vertically flat faced, nevertheless, in a further embodiment of the present invention a “half” element may also be used in designing the elevated structure and giving it a unique appearance. The entire outer periphery of the “half” element comprises an octagonal shape, and possesses a channel formed internally on an underside of the element, with a corresponding singular protrusion also projecting from a top surface of the element. By utilizing a “half” element in constructing an elevated structure, in combination with the regular sized element of the present invention, it is possible to place singular “half elements” on top of a singular protrusion of a regular sized element at staggered, spaced intervals in the elevated structure construction. When, in assembling the elevated structure, full sized elements of the present invention are then further locked or connected on the protrusion of the “half” element, the result is an elevated structure construction which, depending upon the interval between placement of the “half elements”, can provide for gaps in the outer surface of the structure, which enables an aesthetically appealing, unique configuration.

In a further embodiment, in constructing the top surface of the elevated structure, the “half” element can be configured to not possess any protrusions on a top surface portion thereof, so as to provide a “capping element” to enable the top portion of the elevated structure to have a substantially planar surface.
